hey /sci/Bros! I'm trying to teach myself linear algebra, and I stumbled upon this in page 14 of LADR by Axler. What exactly does a set of function from sets S to F look like (F denotes R or C in the book)? I don't quite get this, a function that ranged from say {0, 1, 2} to say {5, 7, 10, 11, 78}? Thanks for the help anons! :)
